About the book: 2021 / After the sudden tragic death of her father, young Nadinka was left an orphan. She also lost the house in which she had lived all her life. Now she has only her faithful nanny Agasha and her beloved Serezhenka. Serezhenka, Sergei Ilyich, is so absorbed in a particularly important project: he is busy building the world's first nuclear icebreaker "Lenin" that he calls from Leningrad so rarely. And poor nanny Agasha doesn’t really believe in the existence of her groom, because she has never seen him. And then to the objective difficulties of the lives of young people are added the problems created by ill-wishers: the talented engineer Sergei with his innovative ideas is declared a pest. Who needs this persecution and why? And will the young people be together??
